PROCESS FOR ORNAMENTING GLA SS.

Application filed July 19,

glass to be used in mirrors, picture mounting and framing, ornamental windows, decorative panels, tableware, etc., and one of its principal objects is to provide an economical and efficient method whereby such articles may be provided with permanent ornamentation of striking beauty.

Another object is the provision of means whereby a sheet of transparent material may be provided upon its rear side with silvered or other light-reflecting surfaces of ornamental design which, when viewed from the front of the sheet, stand out in brilliant relief against a colored background. I

Another object is toprovide economical means for manufacturing glass ornamented as described in the foregoing paragraph, in which the color of the background may be made such as to match interior decorations or to otherwise harmonize with the setting of the piece.

And still another object is the provision of inexpensive ornamental glass pieces of superior beauty.

Other objects and advantages will be apparent from the following description, in which reference is had to the accompanying drawings illustrating a preferred embodiment of my invention and wherein similar reference numerals designate similar parts throughout the several views.

In the drawin s:

Figure I is a ront elevational View of a mirror ornamented according to my invention;

Figure II is a sectional view taken substantially on the line IIII of Figure I.

Referring to the drawings in detail, I have illustrated a mirror ornamented according to'the process of my invention, in which the plate glass 1 is of rectangular shape and is provided on its front side with a beveled edge 2. In the back of the sheet is cut a channel 3 which parallels the bottom and sides of the sheet and is arched adjacent the tion of the sheet l which it is 1923. Serial No. 652,559.

top of the sheet, as at 4. Within the channel 3 are horizontal channels 5 and 6 and vertical channels 7 and 8 which enclose a rectangular field 9. It will thus be seen that the channels form borders which sharply separate different portions of the field. Between the channel 5 and the arched portion 4 of the channel 3 are cut ornamental figures 10 and 11 of geometrical design, and similar figures 12, 13 and 14 are cut in the border formed between the channel 3 and the channels 6, 7 and 8. It is to be understood that the design out upon the back of the glass is illustrative only and that my invention may be employed with anyother design cut in the back of the sheet, whether it be geometrical, conventional, fioral, or otherwise imitative or fanciful, and that the figures of the design may be made by any process capable of making depressions in the glass, such as cutting, engraving, etching, or chipping, or the depressions may be molded or otherwise formed in the glass when the sheet is made.

Having formed depressions of the required shape, the back of the sheet 1 is given a coating of silver 15 or other light-reflecting mater-ial, which, when applied, will cover the entire back of the sheet, or at least that portion of the back of the sheet that is occupied by the depressions. The silver or other refleeting coating which adheres to the lain back of the sheet or that portion of the back of the sheet which is to remain clear or to be colored is next rubbed or polished off with a blocker or other suitable device, leaving the depressions coated with the refleeting substance, as at 16. Since the edges of the de ressions are sharply defined, the edges of tie light-reflecting coating are also sharply defined.

A colored coating of enamel or other suitable substance 17 is'ne-Xt applied to the oresire be colored, and a backing of protective material 18 is then applied over thecoloring material. If any coloring material or protecting material has adhered to the portion 19 of the surface which is to remain clear, it may be rubbed off without-causing the edge of the adjacent design to appear ragged.

In the illustrative form shown, the central field is a mirror surrounded by a border with brilliant raised figures on a colored background, and this border is in turn surrounded by the transparent edge of the glass.

Ill)

In making a combined frame and glass covering for a picture, the silver is removed from'the central field, which is thus left transparent. It is to be understood that any portion of the plain back of the glass may be silvered or left uncovered, or that the entire plain portion of the back may be covered with the colored background ma terial.

' The embodiment of my invention herein shown and described is to be regarded as illustrative only, and it is to be understood that the invention is susceptible to variation, modification and change Within the spirit and scope of the subjoined claims.

Having described my invention, I claim:

1. The process of ornamenting transparent material which consists of forming depressions in the back of such material, coating the surfaces of the depressions and the adjacent back of the material with a lightreflecting substance, removing the light-reflecting substance from a portion of the plain surface of the back adjacent the depressions, and applying a contrasting coating to the portion of the plain surface of the back adjacent the depressions.

2. The process of ornamenting transparent material which consists of forming depressions in the back of such material, coating the surfaces of the depressions and the adjacent back of the material with silver, removing the silver from a portion of the plain surface of the back adjacent the depressions, and applying a contrasting coating to the portion of the plain surface of the back adjacent the depressions.

3. The process of ornamenting transparent material which consists of pressions in the back of such material, coating the surfaces of the depressions and the adjacent back of the material with silver, removing the silver from a portion of the plain surface of the back adjacent the depressions, applying a contrasting coating to the portion of the plain surface of the back adjacent the depressions, and then applying a protective coating over the entire coated back surface. 4. A process for ornamenting transparent material which consists in forming a de pression adapted to constitute a border in the back of such material, coating the surface of the depression and the adjacent back of the material with a light-reflecting substance, and removing the light-reflecting substance from a portion of the plain surface of the back adjacent one side of the depression.

Aprocess for ornamenting transparent material which consists in forming a depression adapted to constitute a border in the back of such material, coating the surface of the depression and the adjacent back of the material with silver, removing the silver'froni a portion of the plain surface of the back adjacent one side of the depression, and applying a contrasting coating to the portion of the silver has been so removed.

A process for ornamenting transparent material which consists in forming a depression adapted to constitute a border and a depression of ornamental design in the back of such materialyapplying a light-refleeting coating to the surfaces of such depressions and to the adjacent plane surface of the back, removing the light-reflecting coating from a portion of the plain surface of the back adjacent said depression of ornamental design, applying a contrasting coating to the portion of the plain surface of the back from which the light-reflecting coating has been so removed, and applying a protective coating over the entire coated back surface.
